In order to improve 4-CP degradation efficiency, a novel gas-liquid hybrid discharge (HD) reactor was developed. Removal of 4-CP with spark-spark discharge (SSD) was higher than that with spark-corona discharge (SCD). Amount of H₂O₂ and O₃ produced with SSD were larger than that with SCD. ·OH formation was increased by the combination of H₂O₂ and O₃.The contribution of ·OH (38% formed by O₃ conversion) oxidation on removal of 4-CP accounted for nearly 60%. The other effects of ultraviolet radiation, intense shock waves and pyrolysis, played partial roles in about 40% of removal rate.
